HEMMING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 715,565, dated December 9, 1902.

Application filed'August 20, 1902. Serial No.120,360. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM E. DURHAM, a citizen of the United States, residing at Port Chester, in the county of Westchester and State of New York, have invented certain new and useful Improvements in I-Iemming At tachments for Sewing-Machines, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide an attachment for sewing-machines whereby plain hemming, hemstitch hemming, imitation-hemstitch hemming, and similar operations may be accomplished, such hems being made of any Width for plain straight Work as on sheets, table-cloths, and similar articles-0r for endless hems, as on pillow-cases or bags, requiring a turned edge at their open fed into my attachment with one hand by the operator, thereby leaving the other hand free for the handling of the bulk of the goods operated upon, which has often heretofore compelled the operator to stop the sewingmachine while arranging the same.

My invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated bysuitable reference characters in each of the views, and in which- Figure 1 is a perspective view of a sewingmachine provided with my hemming attachment, a part of the goods operated upon being also shown in its proper position; Fig. 2, a plan view of the operative part of my invention; Fig. 3, a section on the line 3 3 of Fig. 2; Fig. 4, an end view of an edge turner which I employ; Fig. 5, an elevation of the support of the operative part of my invention; Fig. 6, a section on the line 6 6 of Fig. 5, and Fig. 7 a section on the line 7 7 of Fig. 5.

In Fig. l of the drawings I have shown at a a part of a sewing-machine provided with a face-plate a and the usual table a and adjustably secured to the face-plate 0. by means of screws ofand a isasupport 1), provided with transverse slots 19 and 6 through which the screws a and a are adapted to pass, and the support 19 extends forwardly in the direction of the operator and is provided at its outer end with arms 19 and 11 at the ends of which are guide-blocks b and 22 in which is loosely mounted a rod 0, and secured to the rod 0, by means of a set-screw c and between the guide-blocks b and 19 is a collar 0 which is provided with radially-opposite and downwardlyprojecting lugs and 0 which are adapted to engage with corresponding recesses 19 and b in the guide block W, and the lugs c and c of the collar 0 are adapted to be easily removed from therecesses b and b of the guide-block b Passing around the rod 0 and between the guide-block b and collar 0 is a coil-spring c", which acts to force the collar 0 downwardly against the guide-block b and by means of this construction it will be seen that the rod 0 and collar 0 secured thereto, may be raised and revolved and the lower ends of the lugs c and 0 may rest upon the upper surface of the guide-block b and if the rod 0 andcollar be turned through one-half a revolution the lugs c and a will be forced into the recesses b and b respectively, by means of the coil-spring c", the object of which will be hereinafter explained.

At the lower end of the rod 0 and adjacent to the table a is a base-plate d, which is preferably secured to the rod 0 and extends in its operative position toward the right, and the plate d is provided on its upper surface with a recess d which is angular in form and extends almost the full length of the base-plate d, and the recess d? is preferably about one-half the thickness of the base-plate d, and adjustably secured in the recess 61 is an edge-turner plate (1 which extends beyond the rear side of the base-plate d, and the edge-turner plate 61 is preferably cut away on its under side where it engages the recess (1 of the base-plate d, thereby bringing the upper and lower faces of the said baseplate and edge-turner plate in the same horizontal planes respectively, and the edgeturner plate (1 is also provided with transverse slots (1", 1 and d through which pass screws d (Z and d which engage with the base-plate d.

The edge-turner plate (Z is also provided with a backwardly and downwardly directed groove 6 on its upper face, into which is secured an edge-turning device e secured in the groove 6 by means of screws or bolts 6 and the outer end of the edge-turner 6 projects beyond the side of the plate (1 as shown in Fig. 2, and the said edge-turner e is preferably composed of one piece of metal, the sides of which are bent upwardly and inwardly, as shown in Fig. 4, the member 6 extending partlyover the member 6 and the edge-turner e is tapered toward its outer end in order to bring the turned parts of the goods operated upon more closely together as the said goods pass under the needle or needles of the sewing-machine.

Passing through a longitudinal groove in the bottom of the baseplate d is a guide-bar f provided with an outwardly-directed memberf and at the outerend thereof with a member'f, which is bent at right angles to the memberf and in the same horizontal plane, and on the upper face of the base-plate (Z is a set-screwy, by means of which the guidebar f may be held in any desired position, and at g I have shown a piece of muslin or other goods which is being operated upon, and the body portion thereof is shown as turned over at g the width of such turn being regulated by means of the member f of the guide-bar f and at g I have shown a second turn, which extends a short distance beneath the portion g as shown in Fig. 1.

The operator first places the goods to be hemmed on the table a of the sewing-machine, the bulk of the goods being at the left of the machine, and only as much as is necessary is then drawn underneath the baseplate (Z and guide-bar f and a portion g thereof is then turned over and to the left, and a turn under then being made the portion g is then passed beneath the member 6 of the edge-turner e the portion 9 of the goods passing out between the members eand e and around and beneath the guidef the bodyportion g passing from the guide-arm f beneath the base-plate d and to the left out of the way. The body portion of the goods 9 and the turned portion g which emerges from the edge-turner, are then passed beneath the needle and are stitched together, and the position of the stitch may be regulated by means of the screws d (Z and d. It is only necessary for the operator to feed the goods into the edge-turner, simply keeping a tension on the goods as the same is being drawn beneath the needle, and by means of the screws a and a the entire attachment may be moved backwardly or forwardly and the edge-turner caused to recede from or approach the needle according to the thickness of the material being operated upon.

Should it be desired to remove the baseplate cl from its operative position and out of the way, the rod 0 is forced up, thereby disengaging the lugs c and c from the recesses Z2 and b, and the said base-plate may then be swung into the position shown in dotted lines at h in Fig. 1, and, as will be readily seen, the entire attachment may be easily removed from the sewing-machine or attached thereto at will, and various changes in and modifications of the same may be made without departing from the spirit of my invention or sacrificing its advantages.

From the foregoing description it will be seen that the rod 0 is supported in front of the needle-bar t, a little to the left thereof, and the edge-turner proper of the hemming device, when said device is in position for use, is directly in front of the needle-bart'and the needle supported thereby, and the hemming device and the rod 0 maybe raised and turned out of the way whenever it is desired to use the machine independently thereof.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a sewingunachine of an attachment connected with the faceplate thereofand comprising a support forwardly and backwardly adjustable on said plate, a spring-depressed and vertically-movable rod mounted in said support, and a hemming attachment connected with the lower end of said rod and movable therewith and comprising a base-plate, a transversely-adjustable edge-turning plate connected therewith, an edge-turner connected with the lastnamed plate,and a guide-bar adjustable transversely of the base-plate, substantially as shown and described.

2. The combination with a sewing-machine of an-attachment connected with the faceplate thereof and comprising a support forwardly and backwardly adjustable on said plate, a spring-depressed and vertically-movable rod mounted in said support, and a hemming attachment connected with the lower end of said rod and movable therewith and comprising a base-plate, a transversely-adjustable edge-turning plate connected therewith, an edge-turner connected with the lastnamed plate, and a guide-bar adjustable transversely of the base-plate, said hemming attachment being adapted to be turned in a myinventionl have signed my name, in preshorizonral plane through an arc of one hunence of the subscribing witnesses, this 19th dred and eighty degrees, and means for lockday of August, 1902.
